Unfortunately the current demographics of the USA look far different (worse) than they did in 1984.
1) flood of immigrants (legal and illegal)
2) another 1.5 generations educated in the “progressive” system
Demographics be damned, if people hear it explained over and over again, they tend to understand why conservatism IN ITS ENTIRETY is worth voting for.
When no one puts it forth while everyone else is ridiculing it, putting up straw men against it, it will tend to not receive enough votes.
